WALTER W. STOPPLE, OF ALMA, MICHIGAN, ASSIGNOR TO LITTLE GIANT HAY PRESS COMPANY, OF ALMA, MICHIGAN, A CORPORATION OF MICHIGAN.

BALING-LPRESS.

To all whom it may concern:

Be it known that I, W'ALTER W. S'roPrLn, a citizen of the United States, residing at Alma, in the county of Gratiot and State of Michigan, have invented certain new and useful Improvements in Baling-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to baling presses, and has for an object the provision of improved means for forcing the compression plunger against the matter being baled or compresse Another object of the invention is the arrangement in a baling press, of a tower structure co-acting with an endless chain and a plunger rod for properly conveying power to the plunger head, the chain mounted in the tower structure being associated with power means which continuously rotate the same for moving the plunger forward in successive cycles.

A further object of the invention is the arrangement in a baling press, of a plunger or presser bar formed with an improved pivotally mounted fulcrum and a pair of pivotally mounted hook members, the hook members being guided in their movement by a suitable tower, and caused to move in one direction by the operation of a power chain, and in the opposite direction by one or more retractile springs.

A. still further object is the arrangement in a baling press, of a power wheel having connected therewith a comparatively small pinion meshing with a comparatively large driving gear wheel which cooperates with a chain, tower and plunger for causing the operation of the chain and plunger.

\Vith these and other ob ects in view the invention comprises certain novel constructions, combinations, and arrangement of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings: Figure 1 is a perspective view of an embodiment of the invention. Fig. 2 is a longitudinal vertical section through an embodiment of the invention. Fig. 3 is a detail perspective view of the plun er and associated parts. Fig. 4 is a fragmentary lan view of one of the hooks and part of t e power chain, the same Specification of Letters Yatent.

embodying certain features of the invention. Fig. 5 is a section through Fig. 2 on line 66. Fig. 6 is a section through Fig. 2 on line 77.

In constructing a baling press embodying the invention, the body or compression chamber structure may be of any desired or preferred kind, but preferably arranged with corner members which form partial side, and top, and bottom members. In one end of the compression chamber is arranged an end or stop held in place by suitable clamping members, and against which the prcsser or plunger head forces the matter being baled. At the end opposite the compression chamber is arranged the operating mechanism for propcrly moving the presser or plunger head. This consists principally in the tower structure having an endless chain supported thereby, a plunger or presser pivotally mounted and provided with hook members for engaging the chain, springs for returning the presser head to its original retracted position, and gears, together with a power wheel, for setting in motion the respective moving parts. The power wheel is rotated continuously by any desired power (not shown), which moves the respective gears and moves continuously the chain. The chain is arranged with lugs or projections for engaging the hooks pivotally mounted on the presser or plunger so that upon each downward trip of the lugs on the chain the plunger will be moved down once, and the presser head moved into the compression chamber once. As soon as the lugs on the chain have reached near their lowermost point of movement the same will leave the hooks connected with the plunger so that the springs connected with the plunger may quickly and automatically return the prcsser head to its former position, and the rear end of the plunger to its raised position. This is done quickly in order that the operator may fill the hopper with the matter to be compressed before the lugs on the power chain have reached their uppermost position and commenced their downward journey for again moving the prcsser or plunger. By this arrangement the engine or other power means is permitted to continuously operate, and yet there is a period. of rest for the presser head which provides ample time for forcing into the hopper a proper charge.

In order that the invention may be more clearly understood an embodiment of the same is shown in the accompanying drawings in which 1 indicates a sled structure or other suitable support. Mounted upon the sled structure are a pair of beams 2 and 3 which define at the rear of the machine part of the compression chamber 4, in the center of the machine, part of the hopper 5, and at the front, a base 6, upon which is mounted a mechanism supporting foundation 7. Foundation 7 may be made of any desired kind of material, but preferably is made from metal, and supports the tower 8, and practically all of the power mechanism. The tower is formed with a plurality of uprights 9, 10, 11 and 12. The uprights are constructed preferably of angle irons which are secured to bottom members 13 for holding the tower properly in position. The bottom members are rigidly secured to the bottom of the foundation 7, and the foundation 7 is rigidly secured to the base 6, so thatthe tower is held rigidly in position for resisting any pressure brought thereon, either vertically or horizontally. The angle irons forming the uprights are spaced apart so as to form ways for accommodating guiding lugs or pins 14, 15, 16 and 17 of hooks 18 and 19. The respective lugs are formed at the engaging end of the hook so that the engaging end of the hook may be moved up and down parallel with the respective uprights, while the opposite ends of the hooks are pivoted at 20 and 21 respectively to the presser beam 22. The presser beam 22 is preferably formed from metallic bars 23 and 24, joined by suitable bracing members 25 and 26 (Fig. 2). The front and lower end of the presser beam 22 carries a pivotal bar 27 which engages bearings 28 rigidly secured to the presser head 29. In order to properly guide and act as a fulcrum for the presser beam 22, a pivotally mounted fulcrum 30 is provided pivoted at 31 to beam 22, and at 32 to foundation 7. By this structure whenever the hooks 18 and 19 are raised and lowered the rear end of beam 22 is forced in and out, and consequently the presser head 29 is forced in and out. Auxiliary connecting members 13--13 are connected by bracing and supporting members 33 and 34, to which are secured binding members 35 and 36. The binding members 35 and 36 have connected therewith a pair of uprights 37, and a second pair of uprights 38, which are connected by a suitable blade or fin 39. By the arrangement of the uprights 37 and 38, and the blade or fin 39, a stiffening device is provided for the uprights, and also acts as a guiding means for the power chain 40. The respective links of the power chain 40 are formed so as to straddle the uprights 37 and 38, and are guided thereby, the pins or pintles of the chain resting upon the upspectively as the chain is moved.

rights 37 and 38, so that the lugs 41 and 42 secured to one of the links of the chain will properly engage the hooks 18 and 19 re- As will be noted the lugs 14, 15, 16 and 17 are arranged to slide in the ways formed by the respective angle irons of the uprights 9, 10, 11 and 12, while lugs 41 and 42 are designed to fit into the hook portion of the respective hooks 18 and 19. Arranged below the members 37 and 38 and the fin 39 is a sprocket wheel 43 which is rigidly connected with a shaft 44, the shaft being in turn journaled in suitable bearings in foundation 7. The shaft 44 extends beyond its bearings on one side of the machine, and has rigidly secured to said extended end a gear wheel 45. The gear wheel 45 meshes with a pinion 48 which is rigidly secured to a shaft 49. Shaft 49 is ournaled in suitable'journal members on foundation 7, and extends beyond the foundation 7 on each. side thereof, one end carrying pinion 48, and the other end carrying a power wheel 46, which is preferably a pulley wheel for accommodating a belt 47. Belt 47 receives power from an engine, or other suitable source, and is designed to be continuously moved While the machine is in operation.

By the arrangement of the shaft 49, pulley 46, pinion 48, and gear wheel 45, the machine is geared up suiiiciently to provide a comparatively large amount of power for sprocket wheel 43 when the power applied through belt 47 is comparatively small, so that the machine will compress anything placed therein to the desired extent, without necessitating the use of a powerful engine or other prime mover. The power chain 40 is mounted so as to be moved by sprocket wheel 43, and passes over an upper sprocket 50 near the upper end of the tower 8. The sprocket wheel 50 is mounted on a suitable shaft 51 which is carried by adjustable eyebolts 52 and 53 held properly spaced from the sprocket wheel by spacing rings 54 and 55. The eye-bolts 52 and 53 are threaded at their upper ends and pass through apertures in a suitable bar 56, so that when the nuts 57 and 58 are moved one way or the other the shaft 51 will be adjusted up and down as the case may be for maintaining the prop-er tension on power chain 40. W hen the link of 40 which carries the lugs 41 and 42 over sprocket wheel 50 the lugs engage hook 18 and move the same down until the link carrying the lugs 41 and 42 begins to pass around sprocket wheel 43. As hook 18 is guided in a certain path by the lugs 14 and 15 the same will not follow lugs 41 and 42, but lugs 41 and 42 will move away from the hook, and the hook, together with the presser beam 22, will rise until the forward end thereof has moved to its uppermost position, the same moving under the action of springs 59 and 60. Springs 59 and 60 are connected to the ends of the journal member of shaft 31 and to suitable stops 61 and 62 rigidly secured to the foundation 7. The springs 59 and 60 are arranged to give an almost direct horizontal pull on the springs for the entire travel of the presser beam 22 so as to quickly move the presser beam 22 back to its original position, and the presser head 29 to its original position, before the lugs 41 and s2 can move up to sprocket 50 after the same have moved off of hook 18. The time taken for the lugs 41 and 12 to move up from sprocket 43 to sprocket 50 will be suflicient for the operator to place in the hopper 5 a new charge to be compressed. It will be observed that the presser head 29 is stationary at this time, so that the new charge may be easily placed in position, but the power parts of the mechanism are still operatin This permits the proper feeding of the machine with matter to be compressed, without shutting off the power at any time.

In connection with the construction of the tower 8, the same may be provided with any desired number of braces, as 1313, and the braces may be arranged at any desired distance apart, so as to firmly brace the tower in position. Also suitable braces, as 63, may be added for assisting the tower in resisting any horizontal strain thereon. The hooks 18 and 19, which are guided in their movement by the tower, are arranged so that one hook extends upward, and the other downward, and are formed preferably with a web or fin 64 and 65 respectively for stiffening the hook portion. The springs 59 and 60 will ordinarily return the presser head 29 and the presser beam 22 to their normal positions, but in case the springs should become broken or not accomplish thoroughly this function, the lugs 41 and 42 will engage the hook portion of hook 19, and will positively raise the forward end of the presser beam to its proper height.
